Anyone know? I'm wondering what kind of weight savings I could get by going to a set of Crossmax SL's...

I put CrossMax SLs on my Blur, however had 517's built for the Jekyll. Hugi 240 rear hub, 15/14 double butted spokes and using a Stans Tubeless system on 480 gram tires. It totally changed the Jekyll into a very nimble light feeling bike. The tires are considerably lighter than the CrossMax setup. A similar Mavic rim is a 717. The acceleration when you let off the brakes on a hill is amazing. If you are mostly just trail riding, I'd recommend this setup. I've been riding them for 6 months with no failures (I weigh 160). The CrossMax would probably last you longer, and ride pretty good too.

If you want a great lightweight wheelset, have Mike Garcia at oddsandendos.com build a set of WTB LaserDisc Lites with Velocity VXC rims. I have this set and it weighs under 1600 grams, has not needed a single truing in over 1,000 miles and looks killer too. Much cheaper than Crossmax too.

I would like to know this also. I have the same wheel set on my F600 and would like to get the weight down more. It would also be nice to know if I could feel the difference before I spend that kind of money.

I'm a little confused. Hope you don't mind if I ask a few questions:
What is weight of the new wheels, front and rear? (without tires if possible)
Is the 517 just the rim or a built up wheel? (Mavic's naming/numbering system is confusing)
What kind of a front hub are you using?

I have a Jekyll 600 Disc that I have put Easton monkeylites, a Sette carbon seatpost and TruVativ Team stylo cranks on and the damn thing still weighs 30.2 pounds. There must be a ton of weight to be shed in the wheels if you have yours down to 26.5 pounds...

Yeah, there's no comparison in both weight or performance with the new wheel setup (The rear Hugi 240 hub is one of the lightest made). Also, shed quite a bit of weight with the saddle, carbon seatpost and bars and eggbeater pedals. It just all adds up to a lighter package than my Blur with CrossMax (and 730 gram tires). Basically, the Jekyll frame and front fork weighed no more than the SC frame and Marzocchi fork, so it was just getting all the other "heavy" stock components off the bike.

It's only fitting that I answer my own question since I finally bought a scale. I had Mike Garcia build me a WTB Laser Disc lite/Wheelsmith spokes/Velocity synergy rim for the front. It weighs 759g. I put the stock wheel on the scale and almost fell over - 986g. And that is the front. I can't wait to get the rear done and see how much I can save.

Nice choice, Mike builds ridiculously good wheels. Mine are really light and true as the day I got them.
